Behavior

• Pay 25% of the normal capped kill XP at a five-level gap, then halve for each additional level, rounding down with a 1 XP floor for positive awards.
• Use the credited player's level for solo kills and the rounded-down average of in-room non-pet group members for group kills.
• Keep the threshold configurable through the existing exp_level_difference setting, with a default of five. Penalized kills use their reduced payout for account XP calculations.

Review and validation

• Traced combat credit, party eligibility, PvP and character caps, Happy Hour, account XP, and configuration load/save.
• Widened the gap arithmetic before subtracting legacy mob levels. The production-linked regression covers the boundary, halving, both cap stages, group average, the floor, and an extreme legacy level.
• make -j12 test passed with 2,091 CuTests. make install and the commit and push hooks passed.
• The Experience help matches the flat file and the development database. SQLFluff parsed the companion SQL, and a MariaDB fixture verified that it updates the intended row, matches the flat help, and can be applied twice safely.

Rollout

The existing exp_level_difference value remains in effect when explicitly set. The default applies when the setting is absent. Database-first help installations can apply sql/components/help_kill_experience_falloff.sql when publishing the help change. A rollback restores the prior reward code and Experience help text.
